I figured I'd do the rest as well.

Here is a tarball of all 161 stable 3 point releases from linux-1.0 to 
linux-2.6.39:

211MB:
http://ck.kolivas.org/linux-1.0-2.6.39.tar.lrz

19617064960 linux-1.0-2.6.39.tar
221368298 linux-1.0-2.6.39.tar.lrz 1.1%

As compressing this workload is mostly I/O bound I performed it on an SSD 
drive this time:

linux-1.0-2.6.39.tar - Compression Ratio: 88.617. Average Compression Speed:  
8.026MB/s.
Total time: 00:38:50.76
